== Reason for a new Language ==

Dart is trying to solve JavaScript's problems (which, according to a leaked memo,<ref>[https://gist.github.com/1208618 "Future of Javascript" doc from our internal "JavaScript Summit" last week] - Leaked internal Google email]</ref> cannot be solved by evolving the language) while offering better performance (it's a design goal), the ability "to be more easily tooled for large-scale projects" and better security features.<ref name="GOS20110913">[http://googlesystem.blogspot.com/2011/09/dash-googles-alternative-to-javascript.html Google Operating System: Dash, Google's Alternative to JavaScript]</ref> They are developing a [[Cloud computing|cloud-based]] [[Integrated development environment|IDE]] called Brightly, that will perhaps be the first Dart application. Google will offer a cross compiler that compiles Dart to [[ECMAScript]] 3 on the fly, for compatibility with non-Dart browsers. There will also be a facility to convert [[Type system|typed]] [[Google Closure Tools|Closure]] code to Dart.<ref>[http://www.2ality.com/2011/09/google-dart.html Google Dart to “ultimately ... replace JavaScript”]</ref> Google will also integrate a native [[Virtual machine|VM]] into [[Google Chrome|Chrome]] and encourage competitors to do the same with their browsers. The Dart VM and Dart Cross Compiler could be available in late 2011.<ref name="GOS20110913"/>

== Example ==

main()
{
